Pelvetia canaliculata on sheltered littoral fringe rock
Description (English)
Lower littoral fringe bedrock or stable boulders and mixed substrata in sheltered to extremely sheltered conditions characterised by a dense cover of the wrack Pelvetia canaliculata. The biotope may be present in localised sheltered patches on moderately exposed shores. P. canaliculata overgrows a crust of black lichens Verrucaria maura or the non-calcified red algae Hildenbrandia rubra on very sheltered shores. Individuals of the wrack Fucus spiralis can usually be found among the P. canaliculata and/or in lower part of the biotope. This biotope lacks the density of barnacles found amongst the P. canaliculata on more exposed shores. The winkle Littorina saxatilis occurs, as do a variety of amphipods. The red alga Catenella caespitosa can be present especially in more shaded areas while the green seaweed Enteromorpha spp. can be present in moist areas.
Situation: This biotope is found in the lower littoral fringe on sheltered shores below biotopes dominated by V. maura (unit B3.1132) and above biotopes dominated by F. spiralis (unit A1.212). Though not typical, this biotope may occur on moderately exposed shores where local topography provides shelter.
